Automated Monitoring of Insects ML Platform

Platform for processing and reviewing images from automated insect monitoring stations. Intended for collaborating on multi-deployment projects, maintaining metadata and orchestrating multiple machine learning pipelines for analysis.

Quick Start

The platform uses Docker Compose to run all services locally for development. Install Docker Desktop and run the following command:

$ docker compose up

• Web UI: http://localhost:4000
• API Browser: http://localhost:8000/api/v2/
• Django admin: http://localhost:8000/admin/
• OpenAPI / Swagger Docs: http://localhost:8000/api/v2/docs/

Development

Install the pre-commit tool to run linting & formatting checks before each git commit. It's typical to install this tool using your system-wide python.

pip install pre-commit  # Install pre-commit system-wide
pre-commit install  # Install the hook for our project

If using VS Code, install the formatting extensions that are automatically suggested for the project (e.g. black). Format-on-save should be turned on by default from the project's vscode settings file.

Frontend

Dependencies

• Node.js
• Yarn

Configuration

By default this will try to connect to http://localhost:8000 for the backend API. Use the env var API_PROXY_TARGET to change this. You can create multiple .env files in the ui/ directory for different environments or configurations. For example, use yarn start --mode staging to load .env.staging and point the API_PROXY_TARGET to a remote backend.

Installation

Note: if you installed the ui using Docker first (as instructed in the quick-start) then your local node_modules/ directory will be owned by root. Change the permissions with: sudo chown -R ${UID}:${UID} ui/node_modules. The version of Node on your host machine must match that of the Docker container (which will be the case if you follow the nvm instructions below.)

# Enter into the ui directory
cd ui
# Install Node Version Manager
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
# Install required Node.js version
nvm install
# Install Yarn dependencies
yarn install
# Start the frontend
yarn start

Visit http://localhost:3000/

Backend

Dependencies

• Docker
• Docker Compose

All backend packages are installed in the docker containers, however for faster auto-completion and intellisense, you can install them on the host machine:

python -m venv venv
source venv/bin/activate
pip install -r requirements/local.txt

Helpful Commands

Run the docker compose stack in the background

docker compose up -d

Watch the logs of Django & the backend workers

docker compose logs -f django celeryworker

Watch the logs of all services:

docker compose logs -f

Create a super user account:

docker compose run --rm django python manage.py createsuperuser

Run tests

docker compose run --rm django python manage.py test

Run tests with a specific pattern in the test name

docker compose run --rm django python manage.py test -k pattern

Run tests and drop into interactive shell on failure

docker compose run --rm django python manage.py test -k pattern --failfast --pdb

Launch the Django shell:

docker-compose exec django python manage.py shell

>>> from ami.main.models import SourceImage, Occurrence
>>> SourceImage.objects.all(project__name='myproject')

Install backend dependencies locally for IDE support (Intellisense, etc):

python -m venv venv
source venv/bin/activate
pip install -r requirements/local.txt

Generate OpenAPI schema

docker compose run --rm django python manage.py spectacular --api-version 'api' --format openapi --file ami-openapi-schema.yaml

Generate TypeScript types from OpenAPI schema

docker run --rm -v ${PWD}:/local openapitools/openapi-generator-cli generate -i /local/ami-openapi-schema.yaml -g typescript-axios -o /local/ui/src/api-schema.d.ts

Generate diagram graph of Django models & relationships (Graphviz required)

docker compose run --rm django python manage.py graph_models -a -o models.dot --dot
dot -Tsvg  models.dot > models.svg

Project Data Storage

Each project manages its own external data storage where the AMI Platform will index and process images. This is most typically a public or private S3 bucket at a cloud provider that is not AWS. For example, the Swift object storage service at Compute Canada or a university's own storage service.

To test the S3 storage backend locally, Minio is configured to run as part of the docker compose stack.

To configure a project connect to the Minio service, you can use the following config:

Endpoint URL: http://minio:9000
Access key: amistorage
Secret access key: amistorage
Public base URL: http://localhost:9000/ami/
Bucket: ami

• Open the Minio web interface at http://localhost:9001 and login with the access key and secret access key.
• Upload some test images to a subfolder in the ami bucket (one subfolder per deployment)
• Give the bucket or folder anonymous access using the "Anonymous access" button in the Minio web interface.
• You can test private buckets and presigned URLs, but you will need to add an entry to your local /etc/hosts file to map the minio hostname to localhost.

Email

The local environment uses the console email backend. To view emails sent by the platform, check the console output (run the docker compose logs -f django celeryworker command).

Database

The local environment uses a local PostgreSQL database in a Docker container.

Backup and Restore

docker compose run --rm postgres backup

Reset the database

docker compose run --rm django python manage.py reset_db

Show backups

docker compose run --rm postgres backups

Restore a backup

docker compose run --rm postgres restore <backup_file_name>

Load fixtures with test data

docker compose run --rm django python manage.py migrate
